Question about the sickle and hammer.

[Brandon's Impotent Rage]

OK, so this is probably a bit of a silly question....

We all know the symbol of the crossed sickle and hammer. It's been a symbol of hope for millions of workers (and a symbol of terror for thousands of bourgeoisie), but I've noticed that some groups actually put the two implements on different sides.

We all know the standard:

But I've also seen the tools pointing in different directions, like so:

So I must ask: Is there any significance to the way these tools are facing? Or is it just some sort of stylistic choice?

The right-facing version tends to be favoured by some Trotskyist groups, as in the examples posted.

[Prometeo liberado]

The way in which it is positioned also indicates the amount of time until the emancipation of mankind.
All times being EST of course.
